pipe to the cover and adapted to permit of rotary adjustment of the stand pipe and of tightening the joint from the outside of the completed cell, Without removal of the cover.

The invention Will be claimed at ythe end hereof but .Will be first described in connection With the embodiment of it chosen from other embodiments for the sake of illustration in they accompanying drawings, in Which-- Figure 1, is a top or plan view of a cell embodying features of the invention.

Fig..Q is a sectional view, taken on the line 2 2 of Fig. 1.

Fig. 3, is a side view, drawn to au enlarged scale, and illust-rating the fillingand-ventilating stand pipe.

n. Fig. 4, is atop or plan vieiv of a locking ring.

Fig. 5, is a similar view of a gasket, and

Figs. 6 and 7, are respectively a plan 'view with the stand pipe removed, and a sectional view taken on the line 7-7 of Fig. G.

In the drawings 1 is a stand-pipe that can be used for filling and vcntilating and 2, is a cover provided with an opening 3. There is a right-hand thread on one of these members and a left-hand thread oir the other member. rl`he threads areindicated at -jl and 5; 6, is a locking ring having a right-hand thread on one circumference and a left-hand thread on the other circumference to engage the threads el and 5 of the members 1 and Q. The opening in the cover is notched as at 7 and there is an outward seat 8 tapped With threads 9, is a packing or gasket provided With notches 10 adapted to be alined with the notches 7 The stand-pipe is provided with feathers 11 and with a shoulder 12 upon Which the thread a is formed. rlhe gasket is arranged on the seat 8 and it is approximately Specification of Letters Patent'.

of the same outside diameter as the shoulder 12, so that` space is afforded at 13 under the locking ring 6. The feathers 11 are arranged in the notches .7 and 10` and the locking ring engages Jthe threads 4 and 5 so that the'stand-pipe is rotativelyfixed and endWise movable in respect to the cover and the stand-pipe can be adjusted in the present instancethrough one hundred and eighty circular degrees in order to shift the position of` the fitting 14 by turning the stand-pipe-so that-the fitting 14 lies lin the desired direction prior to the introduction of the feathers 11 in the slots 7 In assembling the parts the gasket 9, which may be of rubber, is first laid in its position on the seat 8 of the cover. The locking ring 6, which may be of hard lead alloy, hard rubber, or the like, is then screwed about one turnonto the thread 4 of the stand-pipe, the latter being preferably a left-hand thread. The stand-pipe ivith the locking ring on it is then placed upon the cover and the feather 11 on the standpipe prevents rotation of the stand-pipe in relation to the cover. The locking ring is then turned ri gilt-handed and as the locking ring enters the thread 5 in the cover, it pulls down on the thread 4 on the stand-pipe A,until the latter reaches and seats upon the rubber gasket. The advantage of doing the work from the top or outside of the cover isv that thevposition of the stand-pipe, or more accuratelyl of the fitting 14, can be changed after the cell is completed Without removing the cover, which is somewhat of a job and in case of leakage the partscan be tightened from the outside Without the necessity of taking off the cover.

It will bey obvious to those skilled in the art to which the invention relates that modifications may be made in details of con- 2.
